| description: | |
| List of regulators provided by this controller. BD71847 regulators node |
| should be sub node of the BD71847 MFD node. See BD71847 MFD bindings at |
| Documentation/devicetree/bindings/mfd/rohm,bd71847-pmic.yaml |
| Regulator nodes should be named to BUCK_<number> and LDO_<number>. The |
| definition for each of these nodes is defined using the standard |
| binding for regulators at |
| Documentation/devicetree/bindings/regulator/regulator.txt. |
| Note that if BD71847 starts at RUN state you probably want to use |
| regulator-boot-on at least for BUCK5. LDO6 is supplied by it and it must |
| not be disabled by driver at startup. If BUCK5 is disabled at startup the |
| voltage monitoring for LDO5/LDO6 can cause PMIC to reset. |
| |
| #The valid names for BD71847 regulator nodes are: |
| #BUCK1, BUCK2, BUCK3, BUCK4, BUCK5, BUCK6 |
| #LDO1, LDO2, LDO3, LDO4, LDO5, LDO6 |
